Summary:

The year 2011 was a good year for search engine marketing. As content became the king, some real impressive search engine optimized websites were developed. Many small and big players around the globe also poured into the domain of search engine marketing.

Google rolled out a solution for the problem that multiple language sites started facing due to Panda filter. This key was in the form of ‘hreflang’ and ‘canonical’ tags. This is Google’s way of telling site owners that they should use a regional subtag in their head tag for the website URL. This will help Google search crawlers to figure out the nature of content on each page and its relevance to a search performed. With these tags on websites, Google will comprehend that content on the site is truly intended for that region.
